LORENZO D. LEWIS, OF ADAMS, NEW YORK.

CAN-COVER.

Specification of Letters Patent.

Application filed February 24, 1910.

Patented July 5, 1910.

Serial No. 545,610.

To all whom it may concern:

Be it known that I, LORENZO D. LEWIS, a citizen of the United States,residing at Adams, in the county of Jefferson and State of New York,have invented certain new and useful Improvements in Can-Covers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to new and useful improvements in covers for cansand receptacles of various kinds and consists in the provision of asimple and eflicient device of this nature so arranged that a secure andhermetically sealed joint may be produced.

The invention comprises various details of construction and combinationsand arrangements of parts which will be hereinafter fully described andthen specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure1 is a sectional view through a can cover and neck of a can showing thecover applied thereto. Fig. 2 is a top plan view of the can. Fig. 3 is abottom plan view of the cover, and Fig. 4: is a top plan View of thecover.

Reference now being had to the details of the drawings by letter, Adesignates the neck of a can having a central opening B therein aboutwhich is an annular rim or beading D. Concentric with said opening is anannular recess E with a space intervening between the same and theannular rim D, which latter projects above the upper marginal openinginto said recess E. About the recess E is an annular flange F projectingabove the surface in which the recess E is formed and said rim F is in aplane coincident with the plane of the upper surface of the rib D.

The cover, designated by letter N, has upon its under face an annularring 0 which is preferably of a diameter a trifle less than the innerdiameter of the recess E in which it is adapted to seat so that theinner marginal edge of the ring 0 will frictionally bind against theinner wall of the recess E to afford a tight joint. Projecting about thecircumference of the annular ring 0 is a circular outlined shoulder Kadapted to rest upon the space intermediate the annular recess E and theinner marginal edge of the flange F and fill such space, whileconcentric with and extending about the shoulder K is the flange Qadapted to rest upon the top of the annular flange F. WVhen the partsare adjusted together, it will be noted that practically a hermeticallysealed joint is afforded.

In order to seal the top, an aperture R is formed through the cover andleading into and adapted to register with a duct T formed through thewall leading into the recess E, as shown by the sectional view, andthrough which a sealing material may be poured in order to fill therecess. A bail designated by letter S is pivot-ally mounted upon eyes Sfastened to the neck at positions diametrically opposite and a cam J isfastened to the bail and adapted to engage the top for the purpose ofholding the bail securely in a locked position.

From the foregoing, it will be noted that, by the provision of a closurefor cans as shown and described, a simple and efficient means isafforded for producing a hermetically sealed joint, thus excluding airfrom the contents of the receptacle.

What I claim to be new is In combination with a receptacle having acircular outlined groove in its end with recesses in the end upon eitherside of said groove and terminating in annular shoulders, a closurehaving a tapering flange projecting from the face thereof and ashouldered portion projecting from the outer face of the flange, saidflange adapted to seat in said groove and the shoulder upon the recessin the end of the receptacle, the outer surface of said closure andcircumference of the receptacle being flush.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
